Since it is shared with the other female side housing 20 which should be fitted to (1), means for avoiding fitting in an incorrect combination is provided. That is, in the device-side housing 10, a rib 16 (an erroneous fitting restricting means, which is a constituent feature of the present invention) extending along the fitting direction of the housings 10 and 20 is formed on the inner periphery of the fitting recess 13. There is. The formation position of the rib 16 in the circumferential direction is set so as to be aligned with the erroneous fitting restriction means on the female housing 20 side to be fitted. The front end of the rib 16 is located rearward of the front end of the hood portion 12, so that the rib 16 does not interfere with the support member when the housings 10 and 20 are fitted together.

Alternatively, with respect to the female housing 20 that is fitted with another male housing (not shown), the position of the restriction groove 24D in the circumferential direction is the female housing 20 shown in the present embodiment.
It is set at a position different from the restriction groove 24D. According to the erroneous fitting restricting means, when fitting the device-side housing 10 and the female-side housing 20 in the correct combination, the position of the rib 16 and the restricting groove 24 are set as shown in FIG.
Since the positions of D are aligned and fitted with each other, the fitting operation of both housings 10 and 20 is allowed. On the other hand, when an attempt is made to combine the female side housing 20 which is an illegal combination with the device side housing 10 of the present embodiment, the position of the restriction groove 24D is relative to the rib 16 as shown in FIG. Since the ribs 16 are disengaged in the circumferential direction, the ribs 16 interfere with the front end of the retainer 24 and the fitting of the housings 10 and 20 is blocked midway. In this way, both housings 1
It is possible to detect whether the combination of 0 and 20 fitting is proper or incorrect.

ストを全体として低く抑えることが可能となっている。In this embodiment, the retainer 24, which is a means for restricting erroneous fitting of the female housing 20, has a housing body 21.
Since it is a separate component from both housings 10,
Even when a plurality of combinations of 20 fittings are assumed, the housing body 21, the wire cover 23, and the lever 29 can be manufactured by one mold as common parts. This is the terminal accommodating portion 28 and the tubular fitting portion 25.
Considering the situation that the cost of the mold of the housing body 21 having a complicated shape and the like is high, the cost of the mold can be reduced. On the other hand, as for the retainer 24, it is necessary to manufacture a plurality of types in which the positions of the restricting grooves 24D are different depending on the combination, but the retainer 24 has a U-shaped mounting portion 24A and a retaining portion 24B in which the through hole 24C is opened. Since it has a relatively simple shape, the die of the retainer 24 is more cost effective than the die for the housing body 21. Therefore, when manufacturing a plurality of types of female-side housings 20 with different regulation grooves 24D, this embodiment can keep the die cost low as a whole.

合わせて短くなっている。Further, the retainer 24, which is an erroneous fitting restricting means of the female housing 20, has a function of preventing the female terminal fitting 22 from being pulled out, in addition to an erroneous fitting restricting function. Therefore, the erroneous fitting restricting means of the female side housing 20 is used as the retainer 2
The number of parts can be reduced as compared with the case where the number 4 is different. In addition, the device body 11 includes a female housing 2
Since there is an extra space for fitting the housing body 21 of No. 0, the equipment-side housing 10 as a whole has a shape recessed inward of the equipment body 11, whereby the tubular fitting portion 25 of the female-side housing 20 is formed. It has been realized that the protruding size of the hood portion 12 that is fitted inside is reduced.
In addition, the protruding length of the tubular fitting portion 25 of the female housing 20 that is fitted onto the hood portion 12 is also shortened in accordance with the protruding length of the hood portion 12.
